好像是鼠标坐标有问题,每次移动窗口就不见了,应该是移动到屏幕之外了.不要用GetCursorPos

#include "windows.h"

#pragma data_seg ("Share")

HHOOK MouseMoveHook=NULL;
POINT point;
BOOL BOOLSetWindowPosHook=FALSE;
HWND SetWindowPosHookhwnd;
#pragma data_seg()
#pragma comment(linker,"/SECTION:Share,RWS")

LRESULT CALLBACK MouseProc(int nCode,WPARAM wParam,LPARAM lParam)
{
if(wParam == WM_MOUSEMOVE)
{
if(BOOLSetWindowPosHook==TRUE)
{
SetWindowPos(SetWindowPosHookhwnd,HWND_TOP,(int)LOWORD(lParam),(int)HIWORD(lParam),0,0,SWP_NOSIZE);
}
}
if(wParam == WM_LBUTTONDOWN)
{
SetWindowPos(SetWindowPosHookhwnd,HWND_TOP,(int)LOWORD(lParam),(int)HIWORD(lParam),0,0,SWP_NOSIZE);

BOOLSetWindowPosHook=FALSE;
}
return CallNextHookEx(MouseMoveHook,nCode,wParam,lParam);
}
_declspec(dllexport)void SetMouseMoveHook(BOOL SetPos1,HWND SetPosHwnd=NULL)
{
BOOLSetWindowPosHook=SetPos1;
if(SetPosHwn

要写成动态链接库程序，才能控制鼠标落入别的窗口的情况。

设 UWM_MOUSEMOVE 是通过 RegisterWindowMessage 注册了的消息
监测 WM_MOUSEMOVE， WM_LBUTTONDOWN。。。。
{
。。。
if(nCode < 0) { /* pass it on */
CallNextHookEx(hook, nCode, wParam, lParam);}

if(msg->message == WM_MOUSEMOVE ||
msg->message == 。。。。)
PostMessage(hWndServer, UWM_MOUSEMOVE, 0, 0);

return CallNextHookEx(hook, nCode, wParam, lParam);
}

钩子哦，不错 不错。
写成DLL吧
